QPECIPICAI'ION forming part of Letters Patent NO. 296,305, dated April8, 1884.-

Application filed February 20, 1884. (No model.)

To a, wit-m it may concern:

Be it known that I, JOHN BAILLIE, of Salem, in the county of Golumbianaand State of Ohio, have invented a certain new and ImprovedBrick-Maghine; and I do hereby declare that the following is a full andcomplete description thereof.

The construction and operation of the brickmachine above alluded to aresubstantially as follows,the description being i ll ustratedby theannexed drawings, making a part of this'specification, in which- Figure1 represents a side elevation of the machine. Fig. 2 is an endelevation. I Fig. 3 is a plan view. Fig. 4 is a transverse sectionthrough the line a: m. Fig. 5 is a longitudinal section. Figs. 6, I, S,and 9 are detached sections.

Like letters of reference denote like parts in the drawings. I

' In and upon a suitably-constructed frame, of which" A. is the top,is'arranged the following-described mechanism: On two opposite sides ofthe top of the frame are secured two pairs of standards, B B and G 0,Figs. 1 and 2, connected to each other, respectively,by the rods 1) andE. Between the said standards is a clamping case or box consisting of averticallymovable top, F, and laterally movable ends G and H, Figs. 1and 3. A reciprocal vertical action is obtained to the top of the caseby means of the following device:

I is a cross head or beam, to which the said top is secured by acentralbolt, a, and side bolts, 2) b, Fig. i. The lower ends of the side boltsdescend through the top of the frame A in bosses, as shown in Fig. 4, inwhich they are closely fitted but free to move, and are guided therebyin their reciprocal vertical movement, actuated by the eccentrics 1 and2, to the rings J J of which they are connected, as seen at c in Fig. 4.

It will be obvious that when the shaft K, on which the eccentrics aresecured, is operated by the lever L the cross-head will be given areciprocal vertical movement, and therewith the top of the case. Theends of the clamping box or case are operated laterally at the same timeby means of a block, M, Fig. i, fitted movably between the sides orwings N of the ends G and H of the case, as shown in said Fig. 4.

in the detached views, Fig. 9.

The standard 0 is removed, that one of the sides or wings of the end Gmay be seen. A top view of the end G or" the case, with the blockbetween the wings thereof, is shown in Fig. 9. On each side of saidblock is an in clined rib, (1, adapted to fit in a correspond ing groovein the sides of the wings N, as seen The block or blocks M M areconnected to the. ends of the cross head or beam I by the screw-bolts O0, respectively, and by which the blocks are given a vertical movementas the cross-head I is operated, and whereby at the same time the blockshave a lateral movement, produced by the inclined ribs working in thecorresponding grooves, which, when the blocks move upward with thecross-head, the inclined ribs move the ends of the case outward, and,per contra, when the cross-head moves downward the inclined ribs forcethe ends inward, for a purpose presently shown.

The rear side of the clamping-ease consists of a sliding carriagecomposed of a bed-plate, P, Fig. 3,'fitted in the opening Q in the top Aof the machine, and supported therein upon rabbets c, on which thecarriage slides longitudinally. On said bed-plate l? are two standingplates, 3 and 4. The plate 4B is fixed to the bed-plate P, whereas theplate 3 is movable toward and away from the fixed plate 4:. The movableplate is attached to the bed-plate by means of a neck, 1%, Fig. 8,)rojectingdownward from said plate through a slot, S, in the bed-plate,and is secured in its connection therewith by a rabbet in the sides ofthe neck, adapted to engage corresponding rabbets in the under sides ofthe edges of the slot, substantially as shown in said Fig. 8.

The object in obtaining to the plate 3 a movable condition willhereinafter be made mani fest.

To the movable plate 3 is attached a handle, T, for moving the saidplate, and also for moving the carriage, of which the plate forms apart, as above said.

U, Figs. 1 and 2, is a bar rigidly connected to the movable plate 3 ofthe carriage. Said bar extends back from the plate to a bloclr,V, inwhich it is fitted closely in a groove therein, and guided initslongitudinal reciprocal movements for moving the carriage. The end ofthe bar U is continued down in the groove of the block V by a slide, f,and by which the length of the stroke of the bar may be lengthened orshortened, as may be required, for a purpose presently shown.' In thesaid slide f is pivoted an angular'lever or pawl, W, the lower end ofwhich is heavier than the upper end or arm, that it may outbalance theupper arm, and thereby tend to keep it in the upright position shown inFig. 5. The lower end of the lever is adapted to engage the shoulderformed on the end of the bar, as seen in Fig. 5. v

To the upper end of the angular lever above alluded to are connected therods y, which extend therefrom forward and under the cross head or beamI and terminate in a single fiattened end, A, Fig. 3, suspended in ahorizontal position by a link, B, depending from an arm, 0, secured toand projecting from the beam 1, as shown in the drawings. As above said,the standing plate 4 of the sliding carriage forms the rear side of theclamping box or case above alluded to. The front side of the caseconsists of the panel 1) of a boxlike slide, E, Figs. 1, 3, and 5,fitted to move in rabbet ways or guides F. Said slide E is operated byeccentrics G G on the shaft H, having its bearings in the standards 1,connected by the brace-rods J to the standards K. The eccentrics alludedto are connected to the slide E by a link L, Fig. 5, secured to theeccentrics by straps M M, and attached to the slide by a hinge-joint, asseen at N in Fig. 5, or by any other suitable j ointconnection. Theeccentrics are operated for actuating the slide E by the lever O,secured to the shaft of the eccentrics.

1?, Figs. 1 and 3, is a shaft having its bearings in the standards K andQ. Close to and on each side of the standard Q, is a link, R. The twolinks are connected to each other by a bar, h, which passes through thestandard in a slot, i, Figs. 6 and 7. The opposite ends of the two linksR are connectedtoa push'plate, j, Fig. 1, having a vertical slot thereinin alignment with the plate 4, so that on moving the push-platej in thetransverse direction of the machine it will pass over the plate 4without interfering therewith.

For operating the push-plate is the purpose of the shaft P, referred to,and which is connected to the bar 71 by means of the arms m m and linksa a, substantially as shown in Figs. 3, 6, and 7, which are conjointlyoperated by the lever S, for actuating the push-plate as aforesaid.

Having described the construction and arrangement of the several devicesconstituting the machine, the practical operation of the same is asfollows:

The machine, as above remarked, is for pressing brick. To this end thebricks are first molded in forms or molds in the usual way. lVhile suchbricks are in a soft condition,

on before the plates 3 and 4, when the carriage is in the position shownin Fig. 3. The bricks are then pushed between the plates, as indicatedby the dotted lines. It will be observed that the space between theplates 3 and4 is wider than the thickness of a brick, and that thedistance from the plate 4 to the edge of the bed-plate is also widerthan the thickness of the brick by so much as the thickness of the sideD of the slide F at the front of the machine. The carriage containingthe bricks is now moved forward into the case under the beam I bypulling upon the handle T. Before the body of the carriage moves, thefirst pull upon the handle draws the plate 3 forward to a stop, which isjust far enough to clamp the sides of the brick a between the two plates3 and 4. A continual pull upon the handle carries the carriage with thebricks into the case,

as above stated. During this forward movement of the carriage to thecase the lever O is in a vertical position, as seen in Fig. 1. Thisposition of the lever has pushed back the rods Y Y by impinging upon theend A thereof, so that the pawl V is lifted above the bar U, asindicated by the dotted lines a in Fig. 1. The carriage and bricks thusmoved into the open case are shown in Fig. 5, in which n a are thebricks. The bricks thus in place, the top F and the ends of the case arenow to be closed for holding the bricks in their normal shape whilebeing pressed. This closing up of the case is done by turning the leverL down in the direction of the arrows, which, by actuating theeccentrics l and 2 and thebloeks M, above described, closes the said topand ends close upon themselves, thereby inclosing the bricks within, sothat when the pressure is applied to them they will retain their propershape and prevent leakage of the material. The pressure upon the bricksis now applied to them by the eccentrics G, and, on turning down thelever O, the eccentrics force the slide E into the case, therebypressing the bricks into a more solid and shapely form than when takenfrom the mold.

That the carriage containing the bricks while under pressure may notrecede in consequence of such applied pressure is the purpose of thepawl XV, and, as the lever 0 begins to move from its vertical position,the connecting-rods Y Y, held back by the said lever,will now moveforward by means of the link B,which, invirtue of gravity, swings to avertical position when the lever is moved away from the end A. Thismovement of the rods brings the pawl down upon the end of the bar U, asseen in Fig. 5. The end of the pawl, being lodged against the shoulder gof the bar, serves for an abutment for the bar, against which to resistthe force of the eccentrics applied to the bricks.

The bricks, when pressed as above described, are then taken out asfollows: A reversement of the movements above described of the machinewill bring the carriage with the pressed bricks to its originalposition. (Shown in Fig.

the brick between the two plates, so that it can- 3.) On pushing backthe carriage to said position the movable plate 3 will,as a consequence,be pushed back to the check 0, therebyreleasi'ng be easily pushed out,together with the brick on the opposite side of the plate ihwhich isfree from confinement. This pushing out the bricks is done by thepressplate j and its operative mechanism above described, and on turningthe lever S in the proper direction, the plate j will push the twobricks out onto the table m, on which they were first placed, and fromwhich they are removed to be replaced'by others for being operated on,as above described.

W hat I claim as my invention, and desire to secure by Letters Patent,is'
